Let the price of car before increase in price was X.  Increase of 12% shall be X x 12/100.  Sum of both shall be:

X + (X x 12/100) = 96320

X + 3X/25 = 96320

[X/1 + 3X/25 = (25X + 3X)/25 = 28X/25]

28X/25 = 96320

X = (96320 x 25)/28 = Rs.86000

can u tell from where does this 28 appear in 3rd line ???
Dear Aslam, I have edited the above reply and shown there how two fractions are added by taking LCM.  [X/1 + 3X/25 = (25X + 3X)/25 = 28X/25].
